Abstract
The utility model relates to a secondary negative pressure dust settler which is a dust removing device suitable for underground coal mining machines in coal mine for reducing coal smoke amount produced when the coal mining machine cuts coal. A nozzle support is arranged on a machine body, a plurality of nozzles are arranged on the nozzle support, the nozzles are communicated with a water inlet pipe, a spraying cover which is a cylindrical body with openings at the front and rear ends is arranged on each nozzle correspondingly. When the dust settler is used, coal dust enters into the spraying cover for forming the secondary dust settlement and improving the dust settling efficiency; the jetting range of water mist is remote and automation effect is good owning to stream guidance function of the spraying cover; moreover, the nozzles are arranged in the machine body, therefore, the nozzle can not be damaged owning to collision, and is durable in use.
Description
Technical field:
The utility model relates to the dust arrester that a kind of suitable colliery silo shearer uses, especially a kind of dust settler that adopts negative pressure to realize final dusting, a large amount of coal smokes that produce when being used to reduce the coal-winning machine coal cutting.
Background technology:
Coal miner spray dust guard under the existing well generally is to adopt water under high pressure directly to spray, and water smoke once contacts dedusting with coal smoke, and has the part coal smoke to be blown to such an extent that fly upward everywhere by it before water smoke arrives, and can not effectively dust be caught, and dust-laying effect is poor.
Summary of the invention:
The purpose of this utility model provides a kind of secondary negative pressure dust settler, solves the defective of the existing direct spray dust prevention device of water under high pressure dust-laying effect difference.
The purpose of this utility model realizes as follows: a body is arranged, and body is used for being connected and fixed with coal-winning machine.Injection nozzle carrier is set on body, plurality of nozzles is set on injection nozzle carrier, nozzle is communicated with water inlet pipe, is covered with spray cap on corresponding each nozzle, and spray cap is the cylindrical shell of front and back end opening.When spraying, the jet place of nozzle forms negative pressure, and coal dust enters in it from the spray cap rear end, mixes forming the secondary depositing dust with water smoke, can improve depositing dust efficient like this.
Spray cap is connected on the nozzle by connector, when regulating the direction of nozzle like this, the spray cap interlock is adjusted.
Injection nozzle carrier and nozzle are arranged on the body inner face.
The beneficial effects of the utility model are: coal dust enters spray cap and forms the secondary depositing dust, has improved depositing dust efficient; And, atomize because the guide functions of spray cap makes the water smoke far firing range; Nozzle is arranged in the body, is difficult for damaged in collision, and is durable in use.
Description of drawings:
Accompanying drawing is the structural representation of the utility model secondary negative pressure dust settler.
The specific embodiment:
With reference to accompanying drawing, at body 1 inner face injection nozzle carrier 2 is set, injection nozzle carrier 2 is made of the hollow section that is interconnected, plurality of nozzles 4 is set on injection nozzle carrier 2, nozzle 4 is communicated with the hollow section of injection nozzle carrier 2, have water inlet pipe 5 to be communicated with the hollow section of injection nozzle carrier 2 in addition, be covered with spray cap 3 by the connector connection on corresponding each nozzle 4, spray cap 3 is the cylindrical shell of front and back end opening.During use, be fixed on the coal-winning machine, connect high-pressure rubber pipe, carry water under high pressure, can normally use by the high pressure pumping plant at the coal-winning machine two ends by bolt hole.The utility model is converted into the steam fog stream barrier of control coal mining machine roller coal cutting dust production resource to external diffusion with water under high pressure, and become local dust-laden air decontamination dust arrester, the purification on the spot that realization is produced dirt to the coal mining machine roller coal cutting, prevention and minimizing dust are to external diffusion.
